4.3.2 Local sense
Fig. 4-3 Local sense connections
The NGMO2 can be connected to operate with local sense leads
(2- wire connection) as shown in Fig. 4-3. When this connection sche-
me is used the sense inputs and supply outputs are jumpered at the
rear of the NGMO2.
4.3.3 Output Impedance
The NGMO2 has a variable output impedance feature on both chan-
nels. This output impedance setting allows the performance of the bat-
tery channel to closely model a real battery’s performance with a dy-
namic load. When setting the output impedance to a certain value (R
I
),
the output voltage drop will be proportional to the output current (see
formula below). The output voltage will be reduced by the voltage drop.
Voltage drop equation: V
drop(t) = R
